The Saturdays star and her rugby player husband Ben Foden will appear on the New Year's Day (01Jan13) episode in a bid to raise money for cancer charities Marie Curie and Niamh's Next Step.

Healy says, "Ben and I are huge fans of the show and have watched it for years. When we were asked if we wanted to play for our chosen charities Marie Curie and Niamh's Next Step, we jumped at the opportunity. We can't wait to take part and hopefully raise lots of money for these great causes."
